FWIW, most decent receivers come with this capability now. The Onkyo I just set up last week had this and I got very familiar with the setup function since I was installing speakers and moving things around a bit at first. Just plug in the mike and it runs a couple test sounds through each speaker. It automatically sets delays based on distance and also frequency cutoffs depending on your speakers.
